Effect of Culture Conditions on Stomatal Density and Stomatal Index in Four Cactus Species
Haseltonia, 2015Abstract: We evaluated type of stomata, as well as differences in stomatal frequency in three areas of the plant (apical, middle and basal) under two culture conditions (in vitro and ex vitro), in four cactus species (Opuntia ficus-indica, Hylocereus undatus, Escontria chiotilla and Mammillaria petterssonii).

Stomatal density of transgenic Arabidopsis thaliana plants over-expressing the SDD1 (stomatal density and distribution) gene was reduced to 40% and in the sdd1-1 mutant increased to 300% of the wild type. CO2 assimilation rate and stomatal conductance of over-expressers and the sdd1-1 mutant were unchanged compared with wild types when measured under ...

The long and the short of stomatal density signals
Trends in Plant Science, 2001Abstract Recent studies have shown that environmental factors such as light and CO 2 are sensed by the mature leaves, which relay this information to developing leaves via long-distance systemic signals. The developing leaves respond by adjusting their stomatal density or stomatal index.

Automatic measurement of stomatal density from microphotographs
Trees, 2014Key message: An automated process using a cascade classifier allowed the rapid assessment of the density and distribution of stomata on microphotographs from leaves of two oak species.[br/]Abstract : Stomatal density is the number of stomata per unit area, an intensively studied trait, involved in the control of CO2 and H2O exchange between leaf and ...

Density gradient centrifugation studies of vesicular stomatitis virus
Archiv f�r die gesamte Virusforschung, 1965Equilibrium sedimentation in caesium chloride has been used to separate and study the biologically active components of vesicular stomatitis virus (Indiana) grown in baby hamster kidney cells and chick embryos. Infective egg fluid was shown to contain two infective components of densities 1.191 g/ml. and 1.217 g/ml.

Stomatal Density Responses to Global Environmental Change
1996The CO2concentration of the Earth’s atmosphere is steadily increasing as a result of anthropogenic activities such as the combustion of fossil fuels and tropical deforestation which release stored carbon from terrestrial sinks. This accumulation of CO2in the atmosphere is the one fact in the global climate change debate upon which all scientists agree (

The cloning and characterization of a poplar stomatal density gene
Genes & Genomics, 2014EPIDERMAL PATTERNING FACTOR1 (EPF1) is a well characterized negative regulator of cell division in Arabidopsis thaliana (AtEPF1) where the pri- mary region of localization is the leaf. However, little data have been reported on the role of EPF1 in other plant species.

Modelling of stomatal density response to atmospheric CO2.
Journal of theoretical biology, 2008Stomatal density tends to vary inversely with changes in atmospheric CO(2) concentration (C(a)). This phenomenon is of significance due to: (i) the current anthropogenic rise in C(a) and its impact on vegetation, and (ii) the potential applicability for reconstructing palaeoatmospheric C(a) by using fossil plant remains.
